package Fcntl;

=head1 NAME

Fcntl - load the C Fcntl.h defines

=head1 SYNOPSIS

    use Fcntl;

=head1 DESCRIPTION

This module is just a translation of the C F<fnctl.h> file.
Unlike the old mechanism of requiring a translated F<fnctl.ph>
file, this uses the B<h2xs> program (see the Perl source distribution)
and your native C compiler.  This means that it has a 
far more likely chance of getting the numbers right.

=head1 NOTE

Only C<#define> symbols get translated; you must still correctly
pack up your own arguments to pass as args for locking functions, etc.
